## Open Gromov-Witten theory on the quintic threefold

**Abstract: **
I plan to discuss the definition of open Gromov-Witten invariants for
Lagrangian submanifolds that arise as the real points of a real symplectic
manifold. To illustrate how the definition works in practice, I will
describe a calculation of the genus zero open Gromov-Witten theory of the
quintic threefold and its real Lagrangian. The result fits nicely into the
general framework of mirror symmetry. This calculation represents joint
work with R. Pandharipande and J. Walcher.
